In a forum topic [0] I was under the impression that the good old uimage-lzma-loader didn't fix the LZMA ERROR 1 for a device. It was found out, that the uimage-lzma-loader never worked because the KERNEL variable was overriden earlier (also an LZMA ERROR 1 related commit, 6fba88de1913), and the "use lzma-loader" fix (commit 09faa73c53bd) didn't catch that to include the "loader-kernel" part. I contributed an LZMA ERROR 1 fix (commit ce1957100411) for the SEAMA device D-Link DIR-860L B1, where I had to duplicate the whole uimage-lzma-loader recipe because of the special needs of the vendor bootloader. This new recipe reuse most of uimage-lzma-loader's KERNEL definiton to avoid duplication. It uses "relocate-kernel" as it needed for D-Link DIR-860L B1 to boot from flash, and it's compatible with D-Link DIR-645 too. It repacks lzma-loader with lzma for kernel (without uImage), because these weird hacked vendor bootloaders accepts only LZMA compressed kernels from flash: We have SEAMA, Image Size = 4759794 Verifying Checksum ... Uncompressing SEAMA linux.lzma ... OK It uses uImage header for initramfs kernel to be little bit verbose. 0: https://forum.openwrt.org/t/136435/10 Signed-off-by: Szabolcs Hubai --- diff --git a/target/linux/ramips/image/Makefile b/target/linux/ramips/image/Makefile index 0992d6ba9f..275251ff6b 100644 --- a/target/linux/ramips/image/Makefile +++ b/target/linux/ramips/image/Makefile @@ -213,7 +213,15 @@ endef define Device/uimage-lzma-loader LOADER_TYPE := bin - KERNEL := kernel-bin | append-dtb | lzma | loader-kernel | uImage none + KERNEL/lzma-loader := kernel-bin | append-dtb | lzma | loader-kernel + KERNEL := $$(KERNEL/lzma-loader) | uImage none +endef + +define Device/seama-lzma-loader + $(Device/seama) + $(Device/uimage-lzma-loader) + KERNEL := $$(KERNEL/lzma-loader) | relocate-kernel | lzma -a0 + KERNEL_INITRAMFS := $$(KERNEL/lzma-loader) | uImage none endef include $(SUBTARGET).mk
